Special properties of new type carbon-copper core-shell nanoparticles composite material fabricated using biomass as template

A new type of carbon-copper core-shell nanoparticles (CCCSNs) have been fabricated using biomass as template. CCCSNs, as made, are homogeneously embedded in carbon black as a composite material. The composite material can be further processed in different dimensions (from hundreds nanometers to meters) based on application needs. The special carbon shells transformed from biomass can protect the copper core from oxidation in ambient environment for years, at the same time; let Cu show the typical antibacterial, antifungal, antifouling properties through it. The CCCSNs made from this innovative technology eliminates the detrimental impacts of conventional engineered nanoparticles usually have and provide the superior properties, including the low cost for fabrication, that conventional copper nanoparticles don´t have.
